This invention relates to new and useful improvements in a tong. v

One objectr of the invention is to provide a tong especially Vadaptedfor use in making together, the sections vof a drill stem,or other pipe,asthesame is being lowered into a well bore, and yfo-r breaking out saidsections as the'drill stem or pipe is being withdrawnfrom the bore, andthe inin particular, means incorporated into the tong for causing saidtong to engage the pipe, or a coupling, Ior tool joint thereof, in suchmanner that the tong will not readily be displaced from the pipe whilein use but may be readily remove therefrom when desired.

With the above and other objects in view, this invention has particularrelation to certain novel features of construction, operation andarrangement of parts examples of which are described in thisspecification 'and illustrated in the accompanying drawings wherein 1 yFigure 1 shows a bottom plan view` of a type lof tong, commonly known asabreakout tong, embodying the invention. Y

Figure 2 shows a sectional view thereof, taken on the line 2--2 ofFigure l. Figure 3 shows an edge view of the tong.V Figure 4 shows aplan view 4of a tubing tong, embodying the invention, as applied to atubing, said view showing also aback up tong as applied to a coupling ofsaid tubing.

" Figure 5 shows a vertical sectional view "of the tubing and the tongsapplied thereto,

as shown in Figure'4, taken on the line 5-5 of said Figure 4, and

va plan view of a back up Y Figure 6 shows as applied tong, 'embodyingthe invention, to a pipe.

Referring now drawings, wherein' j ence design-ate similar parts in eachmore particularly to the like numerals of referof the 'figures thenumeral 1' designates a tong handle whose operative end 2 is beveled andprovided 4with-an engaging jaw 3 prefer- Thereis a clamp 4, arcuate inform', one end of which has spaced fingers 5-5 whi h embrace the handlel and are connected theretoby the pivot pin 6.

one half of a circle of suchdiameter thatsaid face 10 will fit closelyaround said tool 'joint and consequently the-clamp can not slip QE ofthe tool joint laterally, butthe tong must d be elevated untilthe lclampclears the upper end of the tool joint before the tong' can 'be removed.This construction of the clamp willl prevent the displacement .of thetong from the pipe until lit is desired to remove the same." Y

4rThe inner face, orside, l() of the clamp 4 has the engaging jaws ll,1l, adapted to engage the tool joint 9 and, in cooperation with the jaw`3, to turn the upper member ofthe tool joint, Vwhen ately manipulated,and `to thus break the joint, while'the lower section ofthe tool jointis held stationary by means of a back up tong in thewell known manner.

ln Figures 4 and 5 there is illustrated a tubing tong embodying the sameprinciple,

This type of tubing tong has been particularly designed for applicationto tubing having upset, or outwardly thickened ends. This type of tongalso embodies the handle 1, substantially similar" in ,all respects tothat @of the tong shown'in Figures Al to 3. In this form l.the clamp 4is elongatedfeach way handle and is provided at one side spaced fingers5',

' detached from the tubing accidentally or until it is lifted upwardlyto clear the flared portion 12. This type of tong may be re`- versedand, as is obvious, may be usedtfor' screwingthe sections together orunscrewing them. 1 Y v The backuptong shown in Figure 6 embodies thesame principle as that of the break out tong disclosed in Figure 1,having the lhandle 14. withfthe beveled voperating end 15 and the pipeengaging jaw 16 at said operating end. In thistype of tong there is thearcuate clamp 17 pivotally and adj ustably attached to saidhandle. l theopposing inside flanges 18,18 whose inner or free margins are parallel.These free margins are spacedrapart a distance such that the pipe orstemwill fit snugly between them and when the' tong is applied to said pipeabove the tool joint, or coupling, and

moved downwardly the flangesl 18 will rest upon the upper end ,ofsuchtool joint or coupling. The innerside orrface 19 of the clamp describesmore than one half of a circle of such diameter that said face 19 willfit closely around the tool ,joint or coupling, and consequentlyr theclamp can not slip oft' of said joint or coupling laterally butthe tongmust be elevated until the clamp clears the tool joint or couplingbefore the tong can be removed. This clamp 17 may be provided with theengaging jaws 20, 20 which will cooperate with'thehan'dle jaw 16 caus-Vvso applied, the pivot ing the tong to securely engage the pipe orcoupling, asl Ashown in Figures 4 and 5. This back up tong is applied tothe coupling as 13 so as to hold the same while the section of pipeabove is being unscrewed.v While 21 on which the clamp 17 operates willwork through the bearing Asshown in VFigure 6, theback up' tong isapplied Vto the pipe beneath the couplingso as to hold the 'pipeagainstrturning while a lsection above isbeing screwed into the coupling13vwhen the pipe is being made up. `Theiback up tong is applied Yto thecoupling, the Vsection above is screwed homein the coupling,

While thus used, the pivot pin 21 .should bev insertedthrough the bearing 23 of the handle14 soasto adjust the jaw 16 furtherThe clamp 17 has Y whose operative end is adapted to engage the o pipeto Ybe turned, an arcuate clamp open at one side to receive, and formedto surround, the pipe and one end of lwhich is pivoted to said handle,an inside projection carried by said clamp forming Va Ysupport torest'on said coupling, an inside arcuate bearing in said clamp whichdescribes more'thanone half ofa circle and which isof'a diameter greaterthan the outside `diameter 'of the 'pipe and y approximately the same asthat ofl a coupling so as to fit closely about the coupling.
